Black galingale (Kaempferia parviflora), also known as Thai black ginger, is traditionally used in Southeast Asian herbal medicine for a variety of health purposes, including supporting muscle strength and physical performance. In Thai traditional medicine, the rhizome is believed to possess properties that enhance vitality, energy, and overall physical function, which has led to its use among athletes and physically active individuals. The justification for its use to support the muscles body system is rooted primarily in tradition, although there is emerging preliminary scientific interest. A few small-scale studies and animal experiments suggest that black galingale extracts may improve physical endurance and muscle function, potentially through mechanisms related to improved blood circulation, anti-inflammatory effects, and modulation of energy metabolism. However, the quality and scale of the available scientific evidence is limited, with most studies being preclinical or involving small human cohorts with varying endpoints. No large-scale, high-quality clinical trials have confirmed a direct effect of black galingale on muscle strength, hypertrophy, or recovery in humans. As such, while traditional use is well documented, and early research is promising, current evidence does not robustly validate the use of black galingale specifically for muscle support in the context of Western evidence-based medicine.
